Answer:
Explanation:
During an algal bloom the species produce a toxic chemical substance which is harmful to animals that feed on the algae that causes a tint in the water because of the photosynthetic pigments is known as a red tide a red tide may or may not be harmful . Nonetheless algal bloom can produce both beneficial and harmful cycles.
It is beneficial because it can provide organic compounds needed by higher organisms, for this reason productivity increases because there's more algae in the water which means that more carbon dioxide is used from the atmosphere and that more oxygen is being released into the atmosphere which is needed and necessary for many living things
Answer: New research shows that colonies of Escherichia coli can demonstrate a form of learning.
Explanation: Bacterial colonies can evolve the ability to anticipate changes in their immediate environment, say researchers led by Saeed Tavazoie at Princeton University in New Jersey. Other types of bacteria could too. This skill could give them the edge over other bacteria that merely adapt themselves to current conditions.

Answer:
To quote another answer I seen from this same question "I would say that the theme which is reinforced in this excerpt is impossibility of certainty - Hamlet is uncertain what he should do next, and he expresses that uncertainty in this soliloquy. "
Explanation:
Hope this helps :)
<span><u>The answer is A. 72.25 percent.</u>
The Hardy-Weinberg principle can be used:</span>
<em>p² + 2pq + q² = 1</em> and <em>p + q = 1</em>
where <em>p</em> and <em>q</em> are the frequencies of
the alleles, and <em>p²</em>, <em>q²</em> and <em>2pq </em>are the
frequencies of the genotypes.
<span>The <em>r</em> allele (<em>q</em>) is found in 15% of the population:
q = 15% = 15/100
Thus, q = </span><span>0.15
To calculate the <em>R</em> allele frequency (<em>p</em>), the formula p + q = 1 is
used:
If p + q = 1, then p = 1 - q
p = 1 - 0.15
Thus, </span><span>p = 0.85
Knowing the frequency of the <em>R</em> allele (<em>p</em>), it is easy to determine the
frequency of the RR genotype (p²):
p² = 0.85² = 0.7225
Expressed in percentage, p² = 72.25%.</span>
